Overview
Wilton CS4 is a clamp built for the shop, weighing 20 pounds with a footprint of about 10.5 by 5.75 by 7 inches. Its mass and compact stance point to a stationary bench tool rather than something carried between job sites.
Wilton has a long history making vises and clamps for machine shops, and the CS4 fits that lineage more than it fits a portable toolbox. The exact jaw opening and clamping force aren't listed, so shop use should be confirmed against the physical dimensions given.

Who it's for
Fits shop or garage setups where a heavy, stay-put clamp bolted or set at a bench is wanted for metalworking or woodworking. Not a fit for anyone who needs a clamp light enough to move between job sites.
Strengths and trade-offs
Drawn from this product's published specifications.
- Heavy, rigid build suited to stationary bench work
- From a brand with a long history in shop clamps
- Too heavy to move easily between job sites
- Jaw opening and clamping force aren't listed
Performance notes
At 20 pounds, most of the clamp's holding ability likely comes from its own mass and rigidity rather than a stated clamping force, since that spec isn't listed. Its dimensions suggest a clamp meant to stay mounted rather than travel.
